Whether you have just committed murder or are simply trying to fix another ruined pair of panties, getting blood stains out is actually rather simple. The fresher the stain of blood, the easier it will be to get out. If the blood is dried, set and heated, it will be much harder to get out.
Always use COLD water! Never use hot or warm water when getting out a blood stain. It will set the stain harder into the material to where it will be much more difficult to remove. If you are washing blood out of clothing, rub the stains together under cold running water until they fade as much as possible. Then, using light detergent or hand soap, rub the stains until they come out completely. Finish with a thorough rinsing in water. The wetter the fabric, the more the stain may spread, so only wet the part which you will be washing. When washing upholstery, the harder you rub with a cold-water soaked cloth, the more it will come out. Only put a little bit of soap into upholstery, because it will last a long time and you do not want to have that much soap to rinse out once the blood is removed.
Difficult stains. Occasionally, you will have to let a stain dry or a stain will be pretty ingrained into the material. This is when you must soak the material. Run cold water into a container or tub and see to it that all of the stains are completely submerged in the water the entire time. Let it soak for as little as two hours or for up to a day. Keep in mind that if the water drains or evaporates, leaving wet material wadded together in the open air will cause it to become moldy. When it has soaked for a while, try rubbing the blood out again using a small amount of soap. If no progress seems to be made, soak it again.
Keeping things nice. It is the habit of women to leave their underwear soaking in the bathroom sink or in the bathtub. While this is easy and practical, it is not pleasant for men or children to be around. Invest in a small plastic tub, the kind that you would use to soak your feet in. Run your cold water in there, place your garments to soak under the water, and set the tub out of the way. Even though you can put it in a hidden place, it is not recommended to put it completely out of sight. If you forget about it, you may end up with bloodstained and moldy clothing.
If you do not know how to get blood stains out, it is beneficial to be informed, especially since the wrong move can make the stain set deeper. Developing a quick, easy routine for handling such matters can make the lives of you and those around you much simpler.
